WINDOW.

SPECIFICATION forming part of Letters Patent No. 300,136, dated June 10, 1884. 7

Application filed February 12, 1884.

To all whom it may concern.-

Be it known that I, NILs F. SANDELIN, a subjectof Sweden, residing at Chicago, in the county of Cook and State of Illinois, h'ave invented certain new and useful Improvements in Window Sashes and Frames, of which the following is a specification, to wit:

This invention 'relates to an improvement in window frames and sashes; and it consists in a frame and sash of peculiar con-' struction, whereby the sash is more readily handled for cleaning and painting, and is easily and quickly tightened to prevent any rattling, substantially as will be hereinafter more fully set forth and claimed.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referringto the accompanying drawings,in which' Figure 1 is a front elevation of a window sash and frame. Fig. 2 is a transverse section of my frame through the upper sash. Fig. 3 is a similar view taken through the lower sash, showing it in a reversed position. Fig. 4 is a detail view of the jointed parting'strip and its fastening.

A represents a window-frame of any desired size or shape, provided with the upper sash, A, and the lower sash, A, hung with weighted cords a a, and moving in vertical grooves in the frame, separated by the usual partingstrips, a a. At the bottom of the upper sash these parting-strips are cut in two upon a bevel, as at b in Fig. 4, and their lower ends are confined in position by means of small springs b, secured to the bottom of the frame. The lower sash is usually confined in place by a vertical bead nailed to the frame; but inthis case the said sash is upon its inner side provided with a flange, c, which runs in a notch, c, of the frame, and is confined in place by thumb-screws O C, secured in the frame,

and their heads overlapping the flanged sash,

as seen in Figs. 1, 2, and 3. Both sashes are hung by cords in the usual way; but these cordsare brought down alongside the sash and (No model.)

secured thereto near their centers, as seen by dotted lines in Fig. 1.

By reference to the drawings it will be seen that the lower sash is free to be raised or lowered in the usual way, as desired, and when it is desired to clean or paint the sash it may be removed at once by lifting it above the confining-screws, and then drawing it down outside of them, and being hung near its center it may in this position be turned over and replaced in position, as seen in Fig. 3, where it is held while being operated upon, and bot-h sides of the sash can be reached from the inside of the room. The same may be done with the upper sash by pressing down the springs b and drawing out the lower ends of parting-strips, when they are removed, and the upper sash can then be drawn down and out, and treated in the same manner.

The screws 0 C may at any time be tightened to prevent rattling, or loosened to enable a swelled sash to be more freely moved.

Having thus fully described my invention, what I claimas new, and desire to secure by Letters Patent, is-

1. In a window-frame, a sash formed or provided with a flange upon its inner vertical sides, which overlaps the adjoining edges of the frame, in combination witha series of screws secured in the frame beside the flange, and having heads overlapping and confining the same, substantially as and for the purpose set forth.

2. The combination,' with a window-frame, A, provided with the headed screws 0 O and notch c, of a sash having side flanges, c 0, running in said notches, and hung at or near its vertical center by cords a a, whereby it may be more readily cleaned, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
